Description:
Rare copy number variants (CNVs) have a prominent role in the aetiology of schizophrenia and other neuropsychiatric disorders. Substantial risk for schizophrenia is conferred by large (〉500-kilobase) CNVs at several loci, including microdeletions at 1q21.1 (ref. 2), 3q29 (ref. 3), 15q13.3 (ref. 2) and 22q11.2 (ref. 4) and microduplication at 16p11.2 (ref. 5). However, these CNVs collectively account for a small fraction (2-4%) of cases, and the relevant genes and neurobiological mechanisms are not well understood. Here we performed a large two-stage genome-wide scan of rare CNVs and report the significant association of copy number gains at chromosome 7q36.3 with schizophrenia. Microduplications with variable breakpoints occurred within a 362-kilobase region and were detected in 29 of 8,290 (0.35%) patients versus 2 of 7,431 (0.03%) controls in the combined sample. All duplications overlapped or were located within 89 kilobases upstream of the vasoactive intestinal peptide receptor gene VIPR2. VIPR2 transcription and cyclic-AMP signalling were significantly increased in cultured lymphocytes from patients with microduplications of 7q36.3. These findings implicate altered vasoactive intestinal peptide signalling in the pathogenesis of schizophrenia and indicate the VPAC2 receptor as a potential target for the development of new antipsychotic drugs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3351382/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3351382/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vacic, Vladimir -- McCarthy, Shane -- Malhotra, Dheeraj -- Murray, Fiona -- Chou, Hsun-Hua -- Peoples, Aine -- Makarov, Vladimir -- Yoon, Seungtai -- Bhandari, Abhishek -- Corominas, Roser -- Iakoucheva, Lilia M -- Krastoshevsky, Olga -- Krause, Verena -- Larach-Walters, Veronica -- Welsh, David K -- Craig, David -- Kelsoe, John R -- Gershon, Elliot S -- Leal, Suzanne M -- Dell Aquila, Marie -- Morris, Derek W -- Gill, Michael -- Corvin, Aiden -- Insel, Paul A -- McClellan, Jon -- King, Mary-Claire -- Karayiorgou, Maria -- Levy, Deborah L -- DeLisi, Lynn E -- Sebat, Jonathan -- 072894/Z/03/Z/Wellcome Trust/United Kingdom -- GM66232/GM/NIGMS NIH HHS/ -- HG04222/HG/NHGRI NIH HHS/ -- MH044245/MH/NIMH NIH HHS/ -- MH061399/MH/NIMH NIH HHS/ -- MH071523/MH/NIMH NIH HHS/ -- MH076431/MH/NIMH NIH HHS/ -- MH082945/MH/NIMH NIH HHS/ -- MH083989/MH/NIMH NIH HHS/ -- P41 HG004222/HG/NHGRI NIH HHS/ -- P41 HG004222-04S1/HG/NHGRI NIH HHS/ -- P41 HG004222-04S2/HG/NHGRI NIH HHS/ -- R00 HL091061/HL/NHLBI NIH HHS/ -- R01 MH061399/MH/NIMH NIH HHS/ -- R01 MH076431/MH/NIMH NIH HHS/ -- R01 MH076431-06/MH/NIMH NIH HHS/ -- R01 MH082945/MH/NIMH NIH HHS/ -- R01 MH091350/MH/NIMH NIH HHS/ -- England -- Nature. 2011 Mar 24;471(7339):499-503. doi: 10.1038/nature09884.
